3. Duke Energy’s Interoperability Vision
 Committed to interoperability for a sustainable grid
 Collaborated with 25 Coalition partners to demonstrate the value of interoperability
utilizing Open Field Message Bus (OpenFMB™)
 Developed at our innovation center in Mount Holly, North Carolina
 Showcases first OpenFMB plug-and-play integration and optimization of an islandable
microgrid
 Introduces a modular and scalable alternative to federating data between grid edge
devices for operational resiliency

6. OpenFMB – The Industry Catalyst for Interoperability
 Open Field Message Bus (OpenFMBTM) is a reference architecture and framework for
distributed intelligence.
 Leverages existing standards to federate data between field devices and harmonize them
with centralized systems.
 IEC Common Information Model (CIM) for semantic data model
 Internet of Things (IoT) publish/subscribe protocols for peer-to-peer communications
 DDS, MQTT, AMQP
 Allows scaling of operations independently, without a system-wide rollout.
 Flexible integration of renewables and storage with the existing grid
 NAESB’s OpenFMB standard was led by utilities and developed by SGIP.

10. Key Lessons Learned
 Some technologies did not initially produce data to run distributed applications.
 Distributed control sequences need to be choreographed to reflect latencies.
 Time accuracy and synchronization are paramount when operating microgrids.
 Granular and accurate sensor data is important for microgrids.
 Most challenges associated with hardware were resolved with OpenFMB.
 Our vendor partners’ skills and insights refined our final solution.
